摘　　要：1100℃高温锻造工艺是实现高精度金属部件成型的核心工艺,然而其对模具的极端热-力耦合效应导致模具寿命显著降低。文章从材料失效动力学角度出发,构建包含氧化磨损、热机械疲劳(TMF)与塑性变形的多机制协同模型,提出基于热力学参数优化的综合解决方案。通过对比分析H13钢、Mar-M247合金等材料的性能差异,并结合TiAlN-AlCrO梯度涂层的实验结果,证明优化组冷却通道与涂层技术可降低模具表面温升达42.3%,并提升单次服役周期至1852次以上。研究结果为高温锻造模具的长效服役提供理论指导。The 1100℃high-temperature forging process is the core process for achieving high-precision metal component forming.However,its extreme thermal mechanical coupling effect on the mold significantly reduces its lifespan.Starting from the perspective of material failure dynamics,this article constructs a multi mechanism collaborative model that includes oxidative wear,thermo mechanical fatigue(TMF),and plastic deformation,and proposes a comprehensive solution based on thermodynamic parameter optimization.By comparing and analyzing the performance differences of H13 steel,Mar-M247 alloy and other materials,and combining with the experimental results of TiAlN AlCrO gradient coating,it is proved that optimizing the cooling channel and coating technology can reduce the surface temperature rise of the mold by 42.3%and improve the single service cycle to more than 1852 times.The research results provide theoretical guidance for the long-term service of high-temperature forging molds.
